That might explain the slight instability I've noticed on my system since I set it up a couple months ago that doesn't seem to show itself in all circumstances.

I have my PCI locked at 33.3MHz but I don't see a separate control for SATA or IDE dividers/locks in the BIOS. Can someone point me to where it is for this motherboard?

In particular, I am running my 3200+ A64 at 2.4GHz (10x divider, 240MHz I believe) whic his 3800+ speed. The process has no problems at all at this speed and runs pretty cool even with the stock hsf, however I'm concerned something in the motherboard is being overdriven a bit out of spec or whatever. I think it might be the IDE and or SATA channels and I'm wondering where to find the divider/lock for them to get an idea what they're being driven at and if I can reduce it slightly.

Both harddrives I've run (both SATA) have exhibited some sketchy performance and my DVD drive also has as well. Symptoms for the drives are hesitation/refreshing of folders when I open them, Event Viewer shows errors sometimes in the logs as well. DVD drive sometimes stops responding (drive tray eject speed slows down over time and eventually stops opening at all until I fiddle with it a lot and unplug/replug it (while system is off) and then sometimes it starts working again and the drive tray shoots open and closed very quickly at first and then slows down over time. Also when the tray gets slow and/or stops working completely, the drive shows up as a CD-ROM drive and no longer a DVD-R/W drive and I can't use it as a burner. Yes, strange gremlins indeed.
